You will have to enable the TV out in display properties.
Right click over a blank area on your desktop, properties, settings tab, advanced, nVeiw. Choose the output from there.
Probably not going to like the output too much tho.
Edit:
I just relized that it was the VIVO version

. You still have to do the above but make sure you have the proper cable plugged in the "output" on the breakout box. You might find that the card is better for watching the tube on you computer. Use the composite out on your VCR / TV / Etc. to the composite in on the breakout box. Run your sound to the line in on your sound card (maybe labled aux).
